Fairly new and trying to learn so don't hate :)
I have an UNO connected to a sparkfun 16x2 LCD with backpack, spectra softpot, and a controllable RGB led amplifier / 16ft led strip.
I've jumbled together code from various sketches I've come across as well as some of my own and all seemed to work pretty well until I got an lcd attached. I didn't initially notice during my fade tests that each LED was working backwards where "0" was full on and "255" was off. With the LCD it was apparent when I displayed the red LED level and at 255 I had no red. whats the best way to get the correct outputs short of inverting all the values manually? I read about mapping but I dont understand how that would invert it the way Im trying to. Do i need to pull up or down the led pins? What other ways are possible (for learning sake).
I don't want to be given any code, just a little direction to learn.
